| Shell pyramidal, slightly decollated, thin, fragile, moderately shining, blackish-brown, remaining whorls 6½, inflated, with a deep suture; sculpture consisting of flat ridges separated by superficial grooves. Of these ridges there are 5 or 6 on the upper whorls and about 17 on the last whorl, where they reach to the base; the ridges are crossed by more or less distinct lines of growth, which produce here and there small granules, especially towards the upper part of the whorls; last whorl with a varix opposite to the margin of the aperture or slightly backwards. Aperture ovate, outer margin expanded, thickened internally, sinuous and ascending above, produced in the middle, ending in an obtuse angle below; columella with a thin smooth callus, with an... |

| The shells collected by Dr. ten Kate, are from localities which were still very imperfectly or not at all explored. To the latter category belongs the isle of Soemba, which has furnished a few very fine and interesting new species. Other species, though known to science, are remarkable for the novelty of their localities or because the habitat was not yet ascertained. Considering that Dr. ten Kate travelled in behalf of the Dutch Geographical Society and that his chief occupations consisted of geographical and ethnological investigations, the number of species presented to the Leyden Museum must be called important. With respect to the literature, I must remark, that I have usually cited: for the Landshells, the second volume of the Zoological Series of... |

| Shell fusiformly ovate, yellowish, with brown spiral ridges. Whorls about 6, the apical ones, which are slightly eroded, appear smooth, the rest rather convex, depressed near the sutures, vertically ribbed with large swollen ribs of which there are from 10 to 14 on the penultimate whorl, and spirally ridged with 4 or 5 waved ridges on the upper whorls, with finer intermediate ones. On the last whorl, the ribs and waves become obsolete about the periphery; this whorl is encircled with a large number of spiral ridges of which from 10 to 12 form conspicuous brown lirae, with from 1 to 6 intermediate ones. Aperture occupying more than half the length of the entire shell, ovate, pale blue within, lip thickened exteriorly, internally with about 10 ridges forming... |

| The Mollusca enumerated in this paper, have been collected by Dr. L. F. de Beaufort during his stay in our colonies; the majority is from Waigeu. No new species have been named, as the few specimens which are probably new, are in young or in poor condition, but some varietal names have been applied to forms which differ from the types by shape, or which, as for instance in Xesta aulica Pfr. have not been designed by names, as has been done for X. citrina Lin. many years ago, by E. von Martens. I have to thank Mr. G. K. Gude for assistance in naming some doubtful specimens and a few other authorities for the same or for loan of specimens. The few marine species have no special interest. |

| Terwijl de Fauna onzer Oost-Indische bezittingen, wat de zee-Mollusken betreft, vrij volledig bekend mag heeten, en vele der daar levende soorten, tot in de kleinste verzamelingen voorkomen, zijn die der West-Indische Kolonien nog veel minder verspreid. Toen ik werd uitgenoodigd, om een partij schelpen uit de schelpritsen van Suriname te bewerken, was het dan ook niet zonder aarzeling, dat ik die taak aanvaardde. Het hoofddoel waarvoor deze opdracht geschiedde, is echter door mij bereikt, daar het mij bijna zonder uitzondering gelukte, te constateren, dat alle vormen uit de schelpritsen afkomstig en door den Heer Voltz verzameld, nog in West-Indië leven, en dus tot zeer recente vormingen behooren. Behalve in mijn privaatverzameling, kon ik bij een herhaald... |

| In Vol. XVII of this periodical (p. 161, pl. 4, fig. 2) I described and figured as new an Unio, collected by the Zoologist of the Dutch Expedition to Central Borneo, under the name of infrarostratus. Prof. von Martens, whom I sent a copy of my paper, suggested that it might be the same species as U. caudiculatus v. Mart. (Malakozool. Blätter, 1867, p. 16). As this species was not yet figured, and my specimen did not agree in every respect with the description of v. Martens, it was rather easy to make the mistake. Von Martens says: »area postica ad marginem in rostellum parvulum rectangulum procurrente”, and, as the figure in my paper shows, the rostrum is rather large. As to the sculpture v. Martens says: »striae concentricae inaequales, ad angulum... |

| Shell somewhat squarely oblong, moderately inflated, very inaequilateral, covered with a dark-brown fibrous epidermis, giving to the shell the appearance of being concentrically striated; striae coarser towards the margins, if seen by transparent light the colour is yellowish-brown. The umbones being decorticated, no sculpture is perceptible on these parts, but the posterior slope is provided with radiating folds, usually becoming bifurcate towards the margin. Upper margin moderately curved, anterior margin rounded, passing insensibly into the rather straight ventral margin; posterior margin sinuous above, then abruptly truncate, forming two angles, one at the upper part of the truncation and one at the beginning of the ventral margin; from this point an... |

| INTRODUCTION. The Mollusca, recorded in this paper, have been collected by Dr. P. N. VAN KAMPEN and Mr. K. GJELLERUP, during their abode in New Guinea, in 1910 and 1911. The collection is made near the eastern boundary of the Dutch part of the island. „Hollandia" is the name of a camp on the Kajo-bay, a small bay on the western coast of the Humboldtbay, „Hussin" a camp on the Bewani-river, „Zoutbron" (3° 1' 13" s., 140° 57' 30" e.) a camp on the Begouxe-river. The Mbai and Faté are small rivers, which flow in the Humboldtbay near Hollandia, the Tjahé is a small branch of the Mosso. The other localities are to be found on the map which belongs to an article of Capt. Sachse in the „Tijdschrift v. h. Kon. Nederl. Aardrijksk. Gen." (2), dl. XXIX, 1912, p. 36.... |

| In Vol. XVIII, pag. 135, of this periodical I have described a new Melania with the specific name Junghuhni. Now some time ago Prof. K. Martin directed my attention to the fact, that this name was preoccupied for a fossil species, described in 1879/80 in his work: Die Tertiärschichten auf Java; Palaeontologischer Theil, pag. 89, pl. XIV, fig. 20. So his name has the priority, and my species must receive another name, for which I propose Melania Martini, after the person who has detected the error. I may make the apology, that, as it is already not an easy matter to avoid such errors with the names of recent species, it becomes very difficult, to know also the names of the numerous fossils. |

| Shell fusiform, white; whorls 8, slightly concave at the upper part, rather inflated and rounded beneath; nucleus smooth and semitransparent, each of the next whorls with about 10 costae, which become obsolete on the 6th and are entirely wanting on the ultimate and penultimate whorl. The entire surface of the shell, with exception of the nucleus, is covered with close set lines of growth and spiral lirae, of which latter there are 13 on the penultimate whorl, besides a few much finer intermediate ones, which alternate rather regularly with the coarser lirae and are more clearly seen on the ultimate whorl; the lirae are slightly granulate. Last whorl regularly contracted to the base and produced into a moderately long canal, which is slightly curved.... |

| The shells mentioned in this paper, were, for the greater part, collected by Prof. K. Martin on his journey in the East Indian Archipelago, which was undertaken with geological purposes. Another series was brought together by G. W. W. C. Baron van Hoëvell, Resident of Amboyna. This second series contained only a few species, which were, however, represented by a large number of individuals. All these specimens are presented to the Leyden Museum by Messrs. van Hoëvell and Martin. I have included two species from Celebes, though this isle does not belong geographically to the Moluccas. The most interesting part of the collection, consists in the large number of smaller species from a cleft in coral-limestone on Saparoea. From this isle only a few species... |

| Shell elongate, dark fleshy brown, with large white riblike nodules and a white infra-sutural line; whorls 10, the apical ones a little eroded, smooth, the next 2 with rather indistinct ribs, the rest with conspicuous white nodules, which become larger up to the last whorl; on this whorl, which is somewhat oblique, they are smaller on the ventral side, it shows a very large nodule before the aperture and a second row of much smaller ones, which are not visible on the upper whorls. The surface of the shell is covered with faint spiral lirae, which are more distinct on the nodules. Suture linear, irregular in consequence of the nodules of which there are 9 on the last whorl, besides 12 of the second row, and 6 or 7 on the upper whorls, where they occupy... |

| As the reader will see from the head of this paper, the collections are principally made in the interior of the island and therefore almost entirely restricted to terrestrial and freshwater forms. Seven new species have been obtained, while many others are very interesting with regard to the geographical distribution. The few marine specimens, all belonging to common species, have been obtained by Dr. Hallier, the botanist of the expedition, on the Coast of Sambas and the opposite island Lemoekoetan. |

| La collection conchyliologique du Musée d’Histoire Naturelle des Pays-Bas est d’origine très hétérogène. Au premier lieu elle dérive du Cabinet de Zoologie, d’Anatomie Comparée et de Minéralogie de l’Université de Leide, qui surtout sous la direction du professeur Brugmans (1786—1819) s’était énormément développé¹). Une autre collection d’objets d’histoire naturelle, sous le nom de „’s Lands Cabinet” était conservée au Trippenhuis à Amsterdam. Ces collections, combinées avec le Cabinet du Prince Guillaume V et la riche collection d’Oiseaux de C. J. Temminck, forment le noyau du „Ryks Museum van Natuurlijke Historie”, institué par décret royal du 9e Août 1820. En 1822 le Musée s’enrichissait des collections, formées par le Professeur C. G. C. Reinwardt 2)... |

| Shell conic, solid, falsely umbilicate, embryonic whorls wanting, of the 8 remaining whorls the four upper ones are nearly strictly conic, the fifth is slightly, the sixth to eighth strongly constricted at the upper, convex towards the lower part, the last carinated at the periphery, with a flat base, which is however slightly convex towards the aperture; the colour of the shell is white, often with a rosy tinge, with irregular rather broad flames of dark rose on the upper part, where the flames are now broader now narrower than the interstices; on the base the flames are less dark and generally narrower, especially towards the umbilicus; the sculpture of the upper whorls consists of five beaded lirae of which the upper and lower ones are the strongest,... |

| The Mollusks recorded in this paper, have been collected by Mr. J. W. van Nouhuys on Taliabu, one of the larger Xulla-isles, and were presented by him to the Leyden Museum of Natural History, together with a few other species from various localities, amongst which latter are however no new species. As the only record of Mollusks from the Xulla-isles is that of Xesta citrina var. by Wallace, mentioned hereafter in my note on X. halmaherica, I thought it would be interesting to enumerate them all, instead of describing only the new forms. I think the number of species existing in that island will not be exhausted by these 17 species, the more so as the second part of the collection contained several species not represented in the first lot, but the number... |

| Die im Folgenden behandelten Mollusken stammen aus der Nähe von Kajoe ragi auf Celebes, woselbst sie durch R. FENNEMA aus denselben Schichten ausgelesen wurden, aus denen früher durch J. G. DE MAN einige brachyure Krebse beschrieben sind. Es darf deswegen betreffs näherer Angaben über die Herkunft des Materiales auf die Abhandlung des letztgenannten Forschers verwiesen werden¹). Die Schalen befinden sich meistens in sehr gutem Zustande, oft besser erhalten, als man sie in recenten Sammlungen zu sehen bekommt; dennoch hatte es seine Schwierigkeit, sie zu bestimmen, weil so oft kleine Unterschiede von recenten Arten vorkommen, wobei zu entscheiden ist, ob es sich um neue Arten oder um Lokalvarietäten oder nur um Mutationen handelt. Ich hoffe nicht zu viele... |

| The habitat of Nanina (Xesta) inquinata seems still somewhat uncertain. Philippi who described the species for the first time (Abb. u. Beschr. neuer oder wenig gekannter Conchylien I, pag. 10, pl. 4, Helix tab. I, fig. 4) gives Java as locality, on the authority of Mr. Winter; this is followed by Pfeiffer (Monogr. Heliceorum viv. I, pag. 46). The species was not found by Zollinger and has only been mentioned by Mousson (Mollusca von Java, pag. 16). Reeve (Conch. 1c. fig. 399) and even still Clessin (Nomenclator Heliceorum) give Java as locality, though not one of the rather numerous explorers of this isle, had afterwards collected this species. Prof. von Martens (Ostas. Landschn., pag. 207) suggests, after seeing a young specimen in the collection of... |
